Get to the patient story faster
Every address in a health dataset represents a person.
In addition to correcting and geocoding their addresses, Geocodio helps you connect the geographic dots: proximity to care, neighborhood income, social vulnerability indicators, political representation, and more.
And all of it in a single HIPAA-compliant request.
Less time wrangling data. More time on what it means.
From patient addresses to patient insights
(No patience required.)
With just the click of a button, you can enrich your patient address data with heaps of additional data.
All Census data is available at customizable levels. Need demographics at the MSA level? Average household income at the tract level? You got it.

NAACCR North American Association of Central Cancer Registries
"The majority of US cancer registry data is now geocoded through Geocodio. We use Geocodio to geocode our data to support and advance cancer research and control."
Recinda Sherman, Program Manager, Data Use and Research, NAACCR
Who They Are
The North American Association of Central Cancer Registries (NAACCR) is a nonprofit association that provides collaboratively developed data collection standards used by central cancer registries in the US and Canada. NAACCR also produces the Cancer in North America (CiNA) dataset, which informs the American Cancer Society's Cancer Facts & Figures and many other major cancer publications.
Reliable geocoding is critical for geospatial cancer research because it ensures cancer cases are mapped accurately, enabling researchers to identify geographic patterns in cancer burden and more effectively target prevention, screening, and resources.
The Challenge
NAACCR provides geocoding access to its member registries across the US, which is funded by the National Cancer Institute (NCI). The registries process enormous volumes of cancer cases on tight budgets. They needed a new geocoder that was cost effective and that met federal security requirements like SOC 2 and HIPAA/HITECH compliance.
They also needed a geocoder with high accuracy and transparent quality metrics. Poor geocoding can undercount cancer cases for some analyses. For example, in rural areas addresses are harder to geocode and cancer risk is often higher. If rural cases are not geocoded correctly, those communities may receive less funding, fewer screening programs, or less targeted intervention, which may further exacerbate the cancer burden in their communities.
The Solution
NAACCR, in collaboration with the NCI, evaluated multiple geocoders against three criteria: security, accuracy, and cost.
Geocodio offered the best balance of the three.
Geocodio also worked with NAACCR to incorporate additional features, including two of its standard data quality variables, into the SOW. These were delivered on time within the integration.
The Results
Geocodio’s stability, ease of use, and approachable team have made Recinda Sherman, Program Manager, Data Use and Research at NAACCR, a fan. The transition of registry users to Geocodio was seamless, and today, ongoing support needs from members are minimal. "Changing systems is always difficult, but I am very happy we landed with Geocodio," Recinda says.
"Working with Geocodio feels more like a partnership,” she added. “We can reach out, ask questions, and work together. That relationship has been an unexpected, but highly valued, benefit.”
Integrate geocoding into your systems
Geocodio APIs
For real-time patient intake, batch clinical data refreshes, and everything between.
The Geocodio API handles forward and reverse geocoding, address standardization, data appends, and distance calculations through single, batch, and list endpoints.
No code? No problem.
Geocode a spreadsheet
Drag, drop, and pick the data you want added. All of your original columns are exactly where they were beforehand.
All spreadsheet uploads up to 100,000 points come with a map you can layer with Geocodio's data appends and share with your team. No GIS software required.
Ready to clear your compliance review
Geocodio has been through the security and privacy reviews of healthcare systems, health insurers, federal contractors, research universities, and more. These four are where the conversation usually starts.

We started by reviewing summaries of tools other researchers or data users have used. One tool, Geocodio, was listed as one of the best options in some of the online geocoding tool reviews...
Based on our preliminary tests, Geocodio’s performance met our expectations and returned the expected geographic coordinates and additional output elements.
Frequently asked questions
Yes, according to the US Department of Health and Human Services, addresses are considered PHI (Protected Health Information):
All geographic subdivisions smaller than a state, including street address, city, county, precinct, ZIP code, and their equivalent geocodes [are considered PHI], except for the initial three digits of the ZIP code [provided certain conditions are met]
HHS has specific rules for how to de-identify addresses. In no situation is the full address including the street address de-identified—a full address is always PHI.
If you need to standardize or geocode patient addresses, you need to use a HIPAA-compliant geocoder with a signed BAA. Examples of HIPAA-compliant geocoders include Geocodio.
Yes—only if you use a HIPAA-compliant geocoder, or self-host a geocoder in a HIPAA-compliant environment.
According to health researchers, "clinical epidemiology and patient-oriented health care research that incorporates neighborhood-level data is becoming increasingly common."
Geocodio's Enterprise product is one such HIPAA/HITECH-compliant geocoding service.
Yes! Onboarding a new vendor can take time when compliance is involved. So there shouldn't be any surprises about the data you'll get back or how the product works. You should be able to know exactly what you're buying and that it'll work for your needs—before you get Legal and IT Security involved.
Create a free demo account today to try our Enterprise service. You'll get 100 free lookup credits that you can use to try all of our APIs, data appends, and spreadsheet geocoding.
Note: When you're ready to upgrade, we'll sign a BAA. We can't sign BAAs on our Demo plan, so please only use test data. (Need test data? Go ahead and use this list of coffee shop locations.)
When you upgrade to a paid Enterprise plan, you'll be able to keep using the same API key and API endpoints, just with higher throughput.
Yes, you can de-identify addresses so they are no longer PHI—but not the full address. According to HHS, here is how one can de-identify patient addresses:
(B) All geographic subdivisions smaller than a state, including street address, city, county, precinct, ZIP code, and their equivalent geocodes [are considered PHI], except for the initial three digits of the ZIP code if, according to the current publicly available data from the Bureau of the Census: (1) The geographic unit formed by combining all ZIP codes with the same three initial digits contains more than 20,000 people; and (2) The initial three digits of a ZIP code for all such geographic units containing 20,000 or fewer people is changed to 000
